Adhere to all local codes or in their absence
the latest edition of The National Fuel Gas Code
ANSI Z223.1 or NFPA 54 which can be obtained
from The American National Standards Institute,
Inc. (1430 Broadway, New York, NY, 10018) or
National Fire Protection Association, Inc. (Batterymarch Park, Quincy, MA, 02269).
COMBUSTION AND VENTILATION AIR
Heaters installed in these appliances shall
not be installed in a confined space. Heaters
installed in these appliances may be located
in unusually tight construction provided the
space is unconfined, or if confined, is provided
with two permanent openings communicating
directly with an additional room(s) of sufficient volume so that the combined volume
of all connected spaces meets the criteria for
an unconfined space, (National Fuel Gas Code
ANSI Z223.1 1992, Section 5.3). Generally 50
ft 3 per 1,000 BTU input of all operating appliances in the space.
3
The National Fuel Gas Code defines a confined
space as a space whose volume is less than
50 ft 3 per 1,000 BTU/Hr (4.8 m3 per kw) of the
aggregate input rating of all appliances installed
in that space and an unconfined space as a space
whose volume is not less than 50 ft 3 per 1,000
BTU/Hr (4.8 m3 per kw) of the aggregate input
rating of all appliances installed in that space.
Rooms communicating directly with the space
in which the appliances are installed, through
openings not furnished with doors, are considered a part of the unconfined space.
Unusually tight construction is defined as
construction where:
a. Walls and ceilings exposed to the outside
atmosphere have a continuous water vapor
retarder with a rating of one perm or less with
openings gasketed or sealed, and
b. Weather stripping has been added on operable windows and doors, and
c. Caulking or sealants are applied to areas such
as joints around window and door frames,
between sole plates and floors, between
wall-ceiling joints, between wall panels, at
penetrations for plumbing, electrical, and
gas lines, and at other openings.
Use the following equations to determine if you
have a confined or unconfined space.
1. Determine the volume of space — ft 3.
Length x Width x Height = _____ ft 3
(Include adjoining rooms with doorless
passageways or ventilation grills between
rooms).
Example: 24' (L) x 16' (W) x 8' (H) = 3072
ft 3
2. Divide the volume of space by 50 ft 3 to
determine the maximum BTU/Hr the space
can support.
(volume of space – ft 3)/ 50 ft 3 = (Maximum
BTU/Hr the space can support)
3. Add the BTU/Hr of all the fuel burning appliances in the space.

* Do not include direct-vent gas appliances.
Direct-vent is sealed combustion and draws

4. Compare the maximum BTU/Hr the space can
support with the actual amount of BTU/Hr
used.
_________ BTU/Hr
(max. the space can support)
_________ BTU/Hr
(actual amount of BTU/Hr used)
Example:
61,440 BTU/Hr
(max. the space can support)
66,000 BTU/Hr
(actual amount of BTU/Hr used)
The space in the above example is a confined
space because the actual BTU/Hr used is more
than the maximum BTU/Hr the space can support. You must provide additional fresh air.
WARNING
If the area in which the heater may
be operated is smaller than that
defined as an unconfined space,
provide adequate combustion and
ventilation air by one of the methods
described in the National Fuel Gas
Code, ANSI Z223.1 1992, Section
5.3 or applicable local codes.
Example: 3072 ft 3 / 50 ft 3 = 61.44
or 61,440 BTU/Hr the space can support.
4
NOTE: DIAGRAMS & ILLUSTRATION ARE NOT TO SCALE.
Your options are:
a. Rework equations adding the space of adjoining room(s). If the extra volume provides an
unconfined space, then remove door or add
ventilation grills between rooms. Refer to
National Fuel Gas Code, ANSI Z223.1 1992,
Section 5.3.
b. Vent room directly to the outdoors. Refer to
National Fuel Gas Code, ANSI Z223.1 1992,
Section 5.3.
c. Install a lower BTU/Hr heater, such as a 21,000
BTU/Hr, to make the area an unconfined
space.
If the actual BTU/Hr used is less than the
maximum BTU/Hr the space can support, then
the space is an unconfined space. You will
need no additional fresh air ventilation for an
unconfined space.
COLD CLIMATE INSULATION
For cold climate installations, seal all cracks
around the appliance with noncombustible
material and wherever cold air could enter
the room. It is especially important to insulate
outside cavities between studs and under floor
on which the appliance rests, if floor is above
ground level. Gas line holes and other openings
should be caulked with high temperature caulk
or stuffed with unfaced fiberglass insulation. If
the fireplace is being installed on a cement slab,
in cold climates, a sheet of plywood or other
raised platform can be placed underneath to
prevent conducting cold up into the room. It also
helps to sheetrock inside surfaces and tape for
maximum air tightness and caulk firestops.

ASSEMBLY STEPS
Consult all local codes.
Notes:
• Illustrations shown in this manual reflect
“typical” installations with nominal dimensions and are for design and framing reference only. Actual installations may vary due
to individual design preferences. However,
always maintain minimum clearances to
combustible materials and do not violate any
specific installation requirements. Refer to
the Framing Specifications Figures on Page
11.
Properly size and route the gas supply line
from the supply regulator to the area where the
appliance is to be installed per requirements
outlined in the National Fuel Gas Code, NFPA
54 - latest edition (USA) or B149 - latest edition
(Canada). Never use galvanized or plastic pipe.
Gas lines must be routed, constructed and made
of materials that are in strict accordance with
local codes and regulations. We recommend
that a qualified individual such as a plumber
or gas fitter be hired to correctly size and route
the gas supply line to the appliance. Installing
a gas supply line from the fuel supply to the
appliance involves numerous considerations of
materials, protection, sizing, locations, controls,
pressure, sediment, and more. Certainly no one
unfamiliar and unqualified should attempt sizing
or installing gas piping.
• The following steps represent the normal
sequence of installation. Each installation
is unique, however, and might require a
different sequence.
Step 1. Position firebox prior to framing or
into prepared framing.
Step 2. Field wire the main power supply to
the appliance if a blower kit is to be installed
(at the time of installation or a later date).
An optional junction box kit and blower kit is required (see Page 15 for ordering information).
Follow the installation and wiring instructions on
Pages 12 through 14). Electrical connections
should only be performed by an experienced,
licensed/certified tradesman.
Step 3. Plumb gas line. (Gas connections
should only be performed by an experienced,
licensed/certified tradesman).
Step 4. Install decorative type Vent-Free room
heater per the instructions provided with the
Vent-Free room heater.
Step 5. Complete finish wall material, surround and optional hearth extension to your
individual taste.
INSTALLATION
Install 1/2" min. to 1-1/2" max. inside diameter
approved gas line through the firebox wall for
connection to the Vent-Free room heater inside
the firebox. Connect the gas line before the
firebox is enclosed in the finished wall. Gas line
holes and other openings should be caulked with
high temperature caulk or stuffed with unfaced
fiberglass insulation.
Ensure that a sediment trap is installed in the
existing gas line, if not, install a sediment trap
upstream of the heater to prevent moisture
and contaminants from passing through trap
to the heater controls and burners. Failure to
do so could prevent the heater from operating
reliably.
An external regulator must be used on all propane (L.P.G). heaters, in addition to the regulator
fitted to the heater, to reduce the supply tank
pressure to 13" W.C. (maximum). Any copper
tubing used to supply propane (L.P.G). from
the tank must be internally tinned.
WARNING
Gas Line Installation
CAUTION
Plumbing connections should
only be performed by a qualified,
licensed plumber. Main gas supply
must be off when plumbing gas
line to fireplace or performing
service.
8
Remove the gas line access cover plate on either
the left or right side of the fireplace (see Figure
8 showing locations).
Check Gas Type: The gas supply
must be the same as stated on the
heater’s rating plate. If the gas
supply is different, DO NOT INSTALL
the heater. Contact your dealer for
the correct model.
IMPORTANT
Hold heater regulator with a wrench
to prevent movement when connecting to inlet piping.
WARNING
Connecting directly to an unregulated propane (L.P.G). tank can
cause an explosion.
IMPORTANT
Pack unfaced fiberglass insulation
material (not provided) around the
gas line access hole on appliance
and all exterior gas line penetration holes.
TEST ALL CONNECTIONS FOR GAS LEAKS
(FACTORY AND FIELD)
Test all gas joints from the gas meter to the
gas heater regulator for leaks using a gas leak
test solution (also referred to as bubble leak
solution).
Note: Using a soapy water solution as a leak
detection solution is not recommended because
the soap residue that is left on the pipes/fittings
can result in a false-positive leak detection reading
if a gas leak sniffer is used. Soap residue can also
result in corrosion over time.
DO NOT USE AN OPEN FLAME TO CHECK
FOR LEAKS.
Leak Test Procedure:
Turn on gas supply and test for gas leaks using
a gas leak test solution.
A. Light the appliance (refer to the lighting
instructions label provided with gas logs).
B. Brush all joints and connections with the gas
leak detection solution. If bubbles are formed,
or gas odor is detected, turn the gas control
knob (off/pilot/on) to the “OFF” position. Either
tighten or refasten the leaking connection, then
retest as described above.
C. When the gas lines are tested and found to
be leak free, rinse off the leak testing solution
from gas line fittings.

Firebox Framing
Construct firebox framing following Figures
9 through 11 and Table 1 on Page 11 for
your specific installation requirements. Refer to
Figure 8 on Page 10 for firebox dimensions.
The firebox may be installed directly on a
combustible floor or raised on a platform of
an appropriate height. Do not place firebox on
carpeting, vinyl or other soft floor coverings. It
may, however, be placed on flat wood, plywood,
particle board, metal or other hard surfaces
which extend the full width and depth of the
enclosure. Be sure firebox rests on a solid
continuous floor or platform with appropriate
framing for support and so that no cold air can
enter room from under the firebox.
CAUTION
Do not block the heat-circulating
air inlets and outlets on these
fireboxes. Doing so may create a
potential fire hazard.
The firebox may be positioned and then the
framing built around it, or the framing may
be constructed and the firebox positioned into
the opening.
Usually, no special floor support is needed for
the firebox, however, to be certain:
1. Estimate the total weight of the firebox
system and surround materials such as
marble, brick, stone, etc., to be installed
(see Product Referance Table on Page 10
for appliance weight).
3. Note the floor construction, i.e. 2" x 6", 2" x
8" or 2" x 10", single or double joists, type
and thickness of floor boards.
Note: The nailing flange and the area directly
behind the nailing flange is exempt from the
clearances described on the firebox clearance
label.
4. Use this information and consult your local building code to determine if you need
additional support.
Step 4. To safely operate the heater with consideration of the mantel clearances the canopy
must be installed (Model UVF-36 Only).
If you plan to raise the firebox, build the platform assembly then position firebox on top.
Secure the platform to the floor to prevent
possible shifting.
Firebox Installation
Step 1. Frame these appliances as illustrated in
Figures 9 through 11. All framing details must
allow for a minimum clearance to combustible
framing members as shown in Figures 2
through 6. Also refer to appliance specifications
on Page 10 . Headers may be in direct contact
with the appliance top spacers but must not
be supported by them or notched to fit around
them. All construction above the appliance must
be self supporting, DO NOT USE THE APPLIANCE FOR STRUCTURAL SUPPORT.
IMPORTANT
Under no circumstances shall the
firebox top spacers be removed
or modified (see Figure 8). The
header may be in direct contact
with the top spacers but must not
be supported by them or notched to
fit around them.
Top Spacer
Note: The framed depth from a framed wall,
must always be measured from a finished
surface. If a wall covering such as drywall is
to be attached to the rear wall, then the depth
must be measured from the drywall surface. It
is important that this dimension be exact.
8d Nail
Step 2. Level the firebox by checking the top
edge of the firebox. Shim if necessary.
Step 3. Fireplace should be secured to side
framing members using the full length nailing
tabs at the top and bottom of the fireplace front
face. Use 8d nails (see Figure 7).
Figure 7
2. Measure the square footage of the floor
space to be occupied by the system and
surrounds.
